实例01
模拟幼儿园分苹果,代码如下:
def division():
'''功能:分苹果'''
print("\n==============分苹果了================\n")
apple = int(input("请输入苹果的个数:"))
children = int(input("请输入来了几个小朋友:"))
result = apple // children
remain = apple - result*children #计算余下苹果
if remain > 0:
print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。")
else:
print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。")
if __name__ == '__main__':
division()
运行结果如下:
==============分苹果了================
请输入苹果的个数:10
请输入来了几个小朋友:10
10 个苹果,平均分给 10 个小朋友,每人分 1 个。
实例02
模拟幼儿园分苹果(除数不能为0),代码如下:
def division():
'''功能:分苹果'''
print("\n==============分苹果了================\n")
apple = int(input("请输入苹果的个数:"))
children = int(input("请输入来了几个小朋友:"))
result = apple // children
remain = apple - result*children #计算余下苹果
if remain > 0:
print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。")
else:
print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。")
if __name__ == '__main__':
try:
division()
except ZeroDivisionError:
print("\n出错了~_~ —— 苹果不能被0个小朋友分!")
运行结果如下:
==============分苹果了================
请输入苹果的个数:10
请输入来了几个小朋友:0
出错了~_~ —— 苹果不能被0个小朋友分!
实例03
模拟幼儿园分苹果(每个人至少分到一个苹果),代码如下:
def division():
'''功能:分苹果'''
print("\n==============分苹果了================\n")
apple = int(input("请输入苹果的个数:"))
children = int(input("请输入来了几个小朋友:"))
if apple < children:
raise ValueError("苹果太少了,不够分...") #抛出异常(reason)
result = apple // children
remain = apple - result*children #计算余下苹果
if remain > 0:
print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。")
else:
print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。")
if __name__ == '__main__':
try:
division()
except ZeroDivisionError:
print("\n出错了~_~ —— 苹果不能被0个小朋友分!")
except ValueError as e:
print("\n出错了 ~_~ ——", e)
运行结果如下:
==============分苹果了================
请输入苹果的个数:5
请输入来了几个小朋友:10
出错了 ~_~ —— 苹果太少了,不够分...
实例04
模拟幼儿园分苹果(应用断言调试),代码如下:
def division():
'''功能:分苹果'''
print("\n==============分苹果了================\n")
apple = int(input("请输入苹果的个数:"))
children = int(input("请输入来了几个小朋友:"))
assert apple >= children, "苹果不够分" #应用断言调试
result = apple // children
remain = apple - result*children #计算余下苹果
if remain > 0:
print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。")
else:
print(apple, "个苹果,平均分给", children, "个小朋友,每人分", result, "个。")
if __name__ == '__main__':
division()
运行结果如下:
请输入苹果的个数:5
请输入来了几个小朋友:10
